Compare QueryString To AccessDatasource Column Value?
Jul 21, 2009
When my page loads I want to compare the value of a QueryString against the data in a column from an Access Database. I then want to redirect the user to another page if the value of the QueryString does not exist within the column.I thought something like this....
Protected Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs)
If Request.QueryString("ProdID") <> ACCESSDATABASECOLUMN
Then
[code]....
But I do not know what code I should use above where I have "ACCESSDATABASECOLUMN" to pull in the information from the database.
I have a datagrid, with two columns and two rows. The first row is the title of thecolumns, the second is the values. I want to compare the title of the row to a string value, and if it is the same subtract one from the second row value. If it is not the same, compare to the next column title...
Public Sub tickets_left() Night = "Hoodoo" For mm = 1 To 2 'ds.Tables("AddressBook").Columns.Count - 1
I have a Data Table Column with multiple Rows of data. I need to search all lines of TextBox1.Text for any data that is identical to any row in the specified data column ("MCaddRG"). Also any identical findings need to be made into a new text file or a new form with a text box.[code]...
*Also if it is possible I would really like to have a check box list that contains the data from the "Device" columns so I could check the "Device" and then it search the TextBox.Text for the checked "Device's" "MCaddRG"
I've small project to do and now I'm stuck in middle. The program is to read the sequential text file and load it into a array/array of structure.The data information is like this (sample):
ID | Name | Type 1 | Cat | Animal 2 | Dog | Animal
[code]....
This is Just as sample data, my original data is more than this.I've open the DATA.txt file using FileStreamReader:
Dim FileStreamReader As StreamReader = New StreamREader(DATA.txt)
Read all the elements in the list and pass through ReadArrayString.Split the string using:
Where index 0 is the ID, index 1 is the name, and index 2 is the Type Then I load the types in the dropdown combobox menu from the array with out duplication. Like this:
If TypeComboBox.FindString(ReadArrayString(2)) < 0 Then TypeComboBox.Items.Add(ReadArrayString(2)) End If
Now When you click TypeComboBox it will show drop down menu with following list only.
Animal Bird Fish
After this, when Animal type is selected/clicked from combobox dropdown menu then it should only add the Id and Name of Animal type in the ListBox.Pseudocode may looks like this:
If Animal is selected/clicked from TypeComboBox then Add Cat into listbox Add Dog into listbox
[code]....
I've only figure out load items from only one column/array into combobox with out duplication.But can't figure out to compare the value of one column/array with another column/array and load it into listbox. I don't want to hardcode or write matching value inside the code. What I want is use the Array.
Im trying to retrieve some rows from sql server having datetime column that matches the given value of the textbox in a form. The tables datetime column name is "DepDateDepositDate" and the textbox.text was formatted as longdate eg("Tuesday, April 06, 2010") I have this code below but it seems its not retrieving the data that i wanted.
Dim daBnkBok = New SqlDataAdapter("Select * From DepositRef Where Convert(varchar,DepDateDepositDate, 112) = '" & Convert.ToDateTime(clsGlobals.BankBook.bbDepDate.Text).Date & "' ", bbcons)
I am refactoring some legacy code. The app was not using querystrings. The previous developer was hard coding some variables that the app uses in other places.
Like this using VB.NET so.Cpage = "ContractChange.aspx"
i have this querystring that shall open up my page.[URl]..Now when this page loads, on page_load, I want to pick up email and stuid in two different variables. So I can use them to insert into my database (sql server) how can this be done in vb.net
I have a GrideView bound with table,I added one hyperlinkfield as you can see the code below:
<asp:HyperLinkField NavigateUrl="~/Logout.aspx?category=Mobile&&ID=" Text ="logout"/>
As you can see that I am sending 2 QueryString with URL. I am getting both correctly as long as I am sending static data. The problem is that I want to send one of my Grideview column value through QueryString something like this i want and I tried:
<asp:HyperLinkField NavigateUrl="~/Logout.aspx?category=Mobile&&ID='<%GridView1.SelectedRow.Cells(1).Text.ToString%>'" Text ="logout"/>
I am not getting the ID value as per column value but the same Gridview code like this
"GridView1.SelectedRow.Cells(1).Text.ToString".
How should I correct this syntax so i can send my column value through URL.
I am trying to get the QueryString value like this Request.QueryString("SYSTEM") from a UrlReferrer. I see i can use this Request.UrlReferrer.Query() but it doesn't allow me to specify the exact parameter I could parse the Query() value, but I want to know if it is possible to do something like this Request.UrlReferrer.QueryString("SYSTEM")
I have a query string called propID and I wanna check if the passed value in it is a legal integer or not to avoid throwing an error that might reveal info about my database, how can I do it? In other words, I want something like -but in vb.net- : IF QueryString("propID").Content.Type = "int32" Then Proceed
We heard a lot about the vulnerabilities of using QueryStrings and the possible attacks.Aside from that, yesterday, an error irritated me so much that i just decide to stop using QueryStrings, i was passing something like[code]....
My problem is that, I have got below request.querystring
http:[url]......Now I want to pass all the above three querystring in a sql stored procedure parameter.for example,
Try Dim conString As String = WebConfigurationManager.ConnectionStrings("LocalSqlServer").ConnectionString Dim con As New SqlConnection(conString)[code]....
But I am able to get the request querystring value in my parameter.
I am trying to pass a querystring value via the commandargument of a linkbutton. It doesn't seem to be getting the value and just passing the actual text in the commandargument.
I have a requirement where I have to pass some values into the next page via querystring.This querystring is coming from third party and they need to have it on the otherpage for some analysis. I just do a response.redirect and add the querystring that i recieve from them to the other page. My problem is that the .net environment is encoding/encrypting some of the special characters used by them which I dont want as it does not bring back the correct values in the new page.
I have a webpage (OrdersAdmin.aspx) which has various buttons that call the relevant stored procedures and display the results on a grid on the same page. In the grid is a button for each row that when clicked would add a parameter to the querystring, and loads the page. So clicking say first item in the grid would load the OrderAdmin.aspx?OrderID=1. In the page load event it checks to see if there is a OrderID parameter present in the querystring, and if so additional user control is loaded and displayed. The problem is that when I click one of the various buttons again to call the stored procedure this second control that is visible based on presence of OrderID should no longer be displayed.
In my page URL, there is a property taskgrpid - In my code I would like to use the value as an integer. Listed below is the URL from the page and here is my request for the string
I have a form with its method being "get" that passes the variables and their values to the query string, respectively. However, it also passes the viewstate variable in the query string. Now, I have a very long viewstate value on the given page, and if passed in the query string, the viewstate variable will cause the page to error out, due to "too long of a query string" which happens to also be too long of a url.
I cannot merely remove the viewstate variable - I need it. But I need to pass the viewstate variable along via some method other than get when the form is submitted, while the other inputs of the form (the non-hidden inputs) are appended to the query string.
When I do a Request.Querystring("key1") Request.Querystring("key2")
The system doesn't seem to parse the second ?/value out but treats it as if key1 was all one string, e.g. [URL] ...as if it completely ignores or doesn't parse out the second (or other if more) key/value pairs.
I am trying to get the id from a url and send it to the client side this is what I did. This is my url : [URL]
